WATER-CLOSET VALVE.

EiPZ-ZCIPICATION forming part of Letters Patent No, 358,018, datedFebruary 22, 1881 Application filed May 12, 1884. Serial No. 131,237.(No model.)

IO This invention relates to a valvefor regulating the supply of waterto a water-closet; and I it consists in certain features of constructionhereinafter described, and set forth in the claims.

Referring to the drawings, Figure 1 represents a top View of the valve.Fig. 2 showsa vertical section of the same when the valve is closed.Fig. 3 shows a vertical section of the same when the valve is open.

A is the base of the valve,which is adapted to be connected with theinlet or supply pipe. B is the outer casing, which is secured to thebase A, and is provided with an outlet, 1), for connection with the pipefor flushing the waz 5 ter-closet. To the base A is screwed or otherwisecentrally attached a tubular stud, G, having a valveseat, c, the saidstud being surmounted by a plate, D, which is supported by and attachedto ears on the stud. This plate 0 has a screw, (Z, upon which a plate,E, is mounted, and between these plates is placed the packing F, ofleather or other elastic material, the plate E being provided with asquared boss, 6, so the plate can be turned to 3 compress the packingthe desired amount.

G is the valve,having the shape of a bell or inverted cup, and providedwith an annular flange, g, and packing g, which engages the valve-seat awhen the valve is closed. The

top of the valve G has an opening, 9 through which a relief-valve, H,passes, and is" pro vided with a packing, 7L,ll0 f01lll a seat for saidvalve. The relief-valve is shown in the form of a screw,which is tappedinto a spindle, J,

passing upward through the casing B and a stuffing-box, I). A spring, K,surrounds the spindle J and bears upon the stuffing-box and against anadjusting-screw, L, tapped into the upper end of the spindle.

As shown in Figs. 2 and 3, there is a chaniher, M, between the casing Band valve 0, a second chamber, N, between the plate E and the top of thevalve, and a third chamber, 0, between the plate D and valve-flange g g.Vhen the valve is closed, the chamber 0 is filled with watenwhich passesinto it through openings between the plate D and the seatflange c, asshown by arrows in Fig. 2, and the pressure of the water against theflange g 9 (shown by arrows) tends to depress the valve and allow thewater to flow into the chamber M. Such depression of the valveisprevented, however, by water which fills the chamber N, which water haspassed into said chamber by stealing by the packing F when the valve wasclosing, as will be described.

The valve, as a whole, is secured to the hopper of the closet in anypreferred manner,and with the screw L in such relation to the usuallever, which is operated by an elevation of the pull to open the valve,that the spindle J will be depressed by the pressure of said lever onsaid screw. It being desired to flush the closet, the pull is elevatedand the spindle J and relief-valve H are depressed, as shown by dottedlines in Fig. 2, thereby opening the orifice gand allowing the water toflow from the chamber N into the chamber M, as shown by dotted arrow,Fig. 2, as the valve G descends by the pressure of water upon the flangeg 9. During the time the valve is open the movable parts are in theposition shown in Fig. 3, the water flowing into the chamber 0, thenceout into the chamber M and into the outlet 1), as shown by the arrows inFig. 3, a passage being maintained between the bottom of the valve G andthe base A by lugsZon the flange g. The pull having been released, thespring K promptly raises the relief-valve H to its seat 71, as shown bydotted lines in Fig. 3, thereby closing the orifice gi The water underpressure now steals by the packing F from the chamber 0 into the chamberN, as shown by dotted arrows in Fig. 3, and its force is graduallyexerted in the latter chamber to raise the valve G to its seat. Thespeed with which the valve closes under a given pressure is determinedby the closeness of the fit of the packing F to the valve G, and thespeed may be retarded by screwing down the plate E, thereby compressingand expanding the packing, and may be increased by slightly turning upsaid plate. a

If desired, the packing may be made to [it the valve, so that no watercan steal by the packing into the chamber N except through a finevertical groove or grooves made upon the inner surface of the valve G.

As will be understood from the foregoing description and from aninspection of Figs. 2 and 3, the valve G is loosely mounted,withrelation to its seat 0, on the packing F, and is guided by the latter,which construction allows the valve to accommodate itself to its seatand secures a perfect fit between the two.

When the valve is used with a closet having a flushing-tank suppliedwith a float, the spindle J may be pivoted to the float-arm, or bearranged to be pressed upon by said arm,in a manner easily to beunderstood.

What I claim, and desire to secure by Letters Patent, is-

1. In a valve, the combination of an outer casing having an inlet and anoutlet, a hollow stud forming a part of the water-Way, carrying apacking and having a valve-seat, and a flanged bell-shaped valve mountedon said packing, substantially as set forth.

2. In a valve, the combination of an outer casing having an inlet and anoutlet, a hollow stud forming a part of the Water-Way, carrying aflexible packing and having a valve-seat, a flanged bell-shaped valvemounted on said packing, and suitable means, as described, for expandingthe packing, substantially as and for the purposes specified.

3. In a valve, the combination of an outer casing having an inlet and anoutlet, a hollow stud forming a part of the Water-way, carrying apacking and having a valveseat, a flanged -bell -shaped valve mounted onsaid packing and having an outlet-orifice, and a relief-valve foropening and closing said ori- 5 fice, substantially as set forth.
